Numerical solution of differential and integral equations

A physicomathematical model for plasma heating and confinement formulated on the basis of some assumptions on the behavior of a dense plфsma cloud in a magnetic field is presented.

The model allows for ionisation and heating of the deuterium lithium plasma due to heat conduction and heating by a superthermal electron current.

The basic equations include continuity, motion, energy, magnetic field, electric field and ionisation equations.

For numerical solution of the problem, a finite-difference scheme of the type of a universal algorithm with splitting into physical processes and spatial directions is developed, which allowed to obtain separate solutions of the equation of magnetic field, electric field and gas dynamics.

Calculations of the propagation of a plasma cloud heated by a source in an external magnetic field were performed. The mechanism of the effect of the magnetic field and heat source on plasma cloud expansion is determined. The results agree qualitatively with experimental data.
